It uses factual information and analysis, allowing objective and transparent decisions. Its main objective is to identify, prioritize and propose opportunities to improve the portfolio. Opportunities include replacements, migration, modernization, consolidation and decommissioning. APM tools support the people, processes and information of the APM IT discipline to discover, monitor, analyze and visualize the fitness of the application portfolio and provide recommendations for improvement.
